Abstract
The utility model relates to a guide plate suitable for buggy stove, including supply pipe and guide plate, the guide plate matches the junction that sets up in supply pipe and combustion chamber, the pipe wall of guide plate and supply pipe is the angle of certain slope. The utility model discloses the buggy that can make the wind that comes out from the coal -grinding duster and carry is the spiral -flow type and distributes, and it is more even to distribute in the combustion chamber, hot -blast in the combustion chamber evenly distributed, it is more abundant to burn, which saves cost. The effectual emergence of avoiding the phenomenon of catching fire.
Description
Technical field
The utility model relates to drying plant field, particularly relates to a kind of deflector being applicable to coal-powder boiler.
Background technology
Coal-powder boiler take coal dust as the boiler plant of fuel.It has, and burning is rapid, completely, capacity is large, efficiency is high, it is wide to adapt to coal, is convenient to the advantages such as control and regulation.The burning feature of coal-powder boiler is that fuel enters combustion chamber with air, and burns under suspended state.
Coal dust in combustion chamber is lighted by automatic oil spout ignition system by coal-powder boiler.The coal dust of coal-grinding and powder-spraying machine milled is sent in the feed tube chamber of coal-powder boiler by metal hose, and coal dust enters combustion chamber and burns under Action of Wind pressure.The hot-air that burning produces is blown into dryer by the blower fan bottom coal-powder boiler, as the thermal source of dryer.But there is following shortcoming in existing coal-powder boiler:
1, blast skewness in tube chamber of coal-grinding and powder-spraying machine generation, causes the skewness of coal dust;
2, deflector distributes perpendicular to pipeline, can not reduce wind speed and blast, and cause hot blast not uniform in combustion chamber, part coal dust firing is insufficient;
3, hot blast wind speed is very fast, and when wind speed is too fast, portable Mars enters dryer, for easily breaking out of fire easily ignitable material such as oven dry wood chip, Chinese herb residues etc.
Summary of the invention
For the defect that prior art exists, the utility model proposes a kind of deflector being applicable to coal-powder boiler, can make from coal-grinding and powder-spraying machine wind out and the coal dust that carries be that spiral-flow type distributes, in combustion chamber distribution uniform; Hot blast is uniformly distributed in combustion chamber, and ratio of combustion is more abundant; Cost-saving; Effectively avoid the generation of Ignition Phenomena.
For achieving the above object, the utility model proposes a kind of deflector being applicable to coal-powder boiler, comprise feed pipe and deflector; Described deflector coupling is arranged on the junction of feed pipe and combustion chamber; The tube wall of described deflector and feed pipe is in the angle necessarily tilted.
Described deflector is four metallic plates being disposed in an evenly spaced relation in the end of feed pipe.
The tube wall of described deflector and feed pipe is 45 degree of inclination angles.
Beneficial effect:
The deflector of the utility model by arranging, can make from wind and the coal dust that carries be that spiral-flow type distributes, and enters in combustion chamber, and in combustion chamber distribution uniform; Hot blast is uniformly distributed in combustion chamber, and ratio of combustion is more abundant; Cost-saving; Effectively avoid Mars and enter dryer, avoid the phenomenon that the easy breaking out of fire of fire-hazardous material is caught fire.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
1. combustion chamber, 2. deflector, 3. feed pipe.
Fig. 2 is the structural representation of the utility model feed pipe;
2. deflector, 3. feed pipe, 31. feed pipe ends.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in the figure, a kind of deflector being applicable to coal-powder boiler, comprises feed pipe 3 and deflector 2; Described deflector 2 coupling is arranged on the junction of feed pipe 3 and combustion chamber 1; Described deflector 2 is the angle necessarily tilted with the tube wall of feed pipe 3.
Described deflector 2 is four metallic plates being disposed in an evenly spaced relation in feed pipe end 31.
Described deflector 2 is 45 degree of inclination angles with the tube wall of feed pipe 3.
The coal dust of coal-grinding and powder-spraying machine milled is sent into by metal hose in the feed tube chamber of coal-powder boiler, and coal dust burns through the combustion chamber that enters with the spiral board spiral at inclination angle under Action of Wind pressure, and the air-flow after spiral board is the advance of cyclone type.The hot-air that burning produces is blown into dryer by the blower fan bottom coal-powder boiler, and hot blast trend is spiral-flow type, and this hot blast is as the thermal source of dryer.The advantage of this structure has:
1, coal injection pipe and horizontal plane have certain inclination angle, and coal-grinding and powder-spraying machine wind out and the coal dust carried are spiral-flow type distribution, in combustion chamber distribution uniform;
2, deflector and pipeline inclination angle 45 °, can effectively reduce wind speed and blast, hot blast is uniformly distributed in combustion chamber, and ratio of combustion is more abundant;
3, coal dust be evenly distributed in combustion chamber, sufficient combustion, the coal dust used under equal conditions is less, cost-saving.
4, coal dust firing is from dividing, and is not easy to carry Mars and enters dryer, effectively avoid the generation of Ignition Phenomena.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
Claims (3)
